This report evaluates the impact of two types of initiatives for involving real estate developers in building or supporting new child care facilities. These initiatives are: (1) linkage, a legislative mandate that requires developers to construct a child care space or contribute to a child care fund; and (2) bonuses, or zoning incentives that reward developers who build child care facilities. Interviews were conducted with nearly 100 government officials, legislators, city planners, developers, employers, and child care advocates in more than 30 communities which have implemented or are considering some form of developer initiative. Some developers oppose linkage as an unfair tax, and some oppose linkage because of incompatibilities between building codes and requirements for child care. Linkage has increased the child care supply, and improved access to child care. Bonuses are appealing to developers because they are voluntary. Bonuses have resulted in the construction of only seven child care centers. A series of eight recommendations for improving the effectiveness of developer initiatives is offered. Appendixes include lists of contacts for information about linkage and bonuses, and copies of the San Francisco, California, child care ordinance and the Seattle land use director's rule. A 77-item bibliography is provided. (BC)
